Are my suits OK? (Photos)

I recently purchased 2 made to measure suits from a very reputable Japanese retailer (hanabishi). To be honest, I don't know what to think. Admittedly, I'm quite new to menswear and, aside from a couple tailor made suits I got in Vietnam, have little idea as to what a proper fitting suit is supposed to look like.

Some background: I'm looking to embark upon a sales career and searched for a well-wearing material that could put up with some heavy use. I found a couple material samples that I really liked. The store measured me and about 3 weeks later, delivered these suits to my house personally. At that time I didn't have the time to try them on (I know, I know). The pants fit absolutely perfectly but as for the jacket, it strikes me as a bit big and bulky. I understand that the material over the abdomen is supposed to "give" to the size of one fist...it passes this test alright, but I'm in pretty good shape and I feel that I look a bit pudgy in these suits.

I guess what I'm looking for here are some honest opinions. How do these look? If I bring them back to the tailors, what alterations should I request?
